MATLAB Simulation of Various Fiber Bragg Gratings

This document provides detailed information about fiber Bragg gratings along with corresponding MATLAB simulation code to enhance understanding of this subject. The code has been thoroughly tested to ensure correctness, and running the simulations will generate relevant graphical representations of grating characteristics.

A fiber Bragg grating (FBG) is an optical sensor used for measuring physical quantities. It consists of an optical fiber structure with periodic refractive index variations that can measure corresponding physical parameters through transmitted light signals. These gratings are typically created by inducing refractive index changes in the fiber core, commonly manufactured using ultraviolet light or electron beam irradiation techniques.

FBGs have extensive applications including measurement of temperature, strain, pressure, and other physical parameters. They are also utilized in constructing optical devices such as laser frequency stabilizers and fiber light sources.

By executing the following MATLAB simulation code, you can gain deeper insights into the working principles and application scenarios of fiber Bragg gratings.
